NHTSA Complaint #10820387 — 2006 SCION XA

BOUGHT A 2006 SCION XA THAT PREVIOUSLY HAD THE CHARCOAL CANISTER ASSEMBLY AND FUEL FILLER PIPE COVER REPLACED UNDER TSB EG047-06. CEL WAS ON WHEN I BOUGHT THE CAR, AND THE CODES P043E, P043F, P2401, P2401, P2419 INDICATED THE SAME COMPONENTS WERE DAMAGED AGAIN. I REPLACED THE COMPONENTS AFFECTED BY THE TSB, WHICH INCLUDED UN UPDATED PART NUMBER FOR THE FUEL TANK FILLER PIPE COVER HOLDER (77248-52050). AFTER CLEARING THE CODES, THE CAR WAS FINE FOR SEVERAL THOUSANDS OF MILES UNTIL THE CEL CAME BACK ON WITH THE SAME CODES. IT DOESN'T MAKE SENSE TO CONTINUE REPLACING THE CHARCOAL CANISTER EVERY TIME THESE CODES REAPPEAR. I CANNOT FIND ANY NEW INFORMATION TO INDICATE TOYOTA HAS A PERMANENT FIX FOR THIS RECURRING ISSUE, AND I HAVEN'T COME ACROSS ANY ALTERNATE FIX ON THE INTERNET THAT RESOLVES IT. I AM CONTEMPLATING SOME SORT OF WORK AROUND TO SEAL THE CANISTER AND THE ELECTRICAL CONNECTIONS TO PREVENT THE WATER INTRUSION INTO THE CANISTER, BUT I ALSO DON'T WANT TO DOING ANYTHING THAT WILL PREVENT THE CANISTER FROM FUNCTIONING PROPERLY. I ALSO DON'T WANT TO IGNORE THE CEL IN THE EVENT THE CEL STORES OTHER CODES UNRELATED TO THIS ISSUE.
